Ridge Expansion:

Date: January 28-29, 2011

Cost: $1995  CE Credits: 14

Ridge expansion techniques have been developed to improve results and shorten treatment time with simultaneous implant insertion. Ridge expansion utilizes the biologic healing potential of bone like an extraction site, to restore the functional proportions of the dento-alveolar complex. Recent application of new technologies including; ultrasonic bone cutting, mechanical expanders and implant designs have simplified treatment of mandibular horizontal deficiencies. In the Maxilla a non-traditional approach to incision design and flap development is necessary to preserve the periosteal micro-vascular supply of the alveolus. Sinus floor elevation can be completed at single or multiple adjacent sites using modified “osteotome” or “contiguous sinus floor elevation” techniques.  With ridge expansion, a vascular “bone flap” is developed and can allow trans-alveolar access to the sinus floor.  Sinus floor access can also be gained through an extraction site and at adjacent edentulous areas. Significant sinus elevation can be obtained using these techniques with implant placement. The advantages of these minimally invasive techniques are; excellent esthetics, minimal discomfort, avoiding grafting or barriers, decreased healing interval and eager patient acceptance. These approaches will be reviewed including periosteal preservation, indications, contraindications, intra-operative decision-making and the management of complications. A rational approach to the introduction and progressive implementation of the techniques will be discussed.
